Not able to change java home path in wildfly 9.0.2

[nish18]

Hi ,

I am using java 8 and when I am trying to deploy war file on wildfly server . Its giving error :

Caused by: java.lang.UnsupportedClassVersionError: demo/Demo_Servlet : Unsupported major.minor version 52.0

  at java.lang.ClassLoader.defineClass1(Native Method)

My system variable and all java path are set properly to java 8.

Only java home path for wildfly server is set to java 7. I tried to changed it through admin console of wildfly server.

On clicking on edit, it again change back to java 7 path.Changes are not getting updated.

Can someone please help on this.

Did you set the JAVA_HOME to point to JDK 1.8 installation inside the   "wildfly-9.0.2.Final/bin/standalone.conf"    (on WINDOWS edit the file "standalone.conf.bat" ) instead.

Unix Based OS "standalone.conf"

JAVA_HOME="/PATH/TO/jdk1.8.0"

Windows Based OS "standalone.conf.bat"

set "JAVA_HOME=C:\opt\jdk1.8.0"
set "JAVA=C:\opt\jdk1.8.0\bin\java"

If you are in domain mode then you can define the JAVA_HOME for individual servers inside the    "host.xml" file  as following:

    <servers>
        <server name="server-one" group="main-server-group">
            <jvm name="test" java-home="C:\opt\jdk1.8.0" />
        </server>
        .
        .
    </servers>
